Title: Method for detecting compaction status of asphalt pavement during construction compaction
Inventor: GUOPING QIAN
IPC: E01C19/23
Filed: 2020-05-20
Abstract: The present invention discloses a method for detecting a compaction status of an asphalt pavement during construction compaction. The method mainly includes the following steps: using a device for detecting compaction and shear strength characteristics of the asphalt mixture; pressing a test claw into the asphalt mixture during construction; rotating the test claw slowly and uniformly to measure an internal temperature and a shear characteristic of the mixture during paving and subsequent compaction; calculating a corresponding compaction detection index based on the shear characteristic; and monitoring and guiding the construction quality and construction process accordingly based on the real—time detection index. The present invention measures the compaction detection index of the asphalt mixture during compaction simply, quickly and accurately. The present invention uses the compaction detection index together with a degree of compaction for dual control of asphalt pavement compaction. The two indexes are used to accurately evaluate a compaction effect of the asphalt mixture and determine a compaction status of the asphalt mixture during construction.

Title: Gas detector and analyser using electromagnetic radiation - has magnetic field in chamber absorbing wavelengths of lines of unknown gas
IPC: G01N21/31
Filed: 1976-11-09
Abstract: The instrument, can be used to detect and measure the components of a gaseous mixture. It uses electromagnetic radiation, such as UV visible or IR radiation.

Filed: 1994-08-04
Abstract: The invention provides pectins as new foam stabilizers for (temporary) foam heads in beverages, in particular in beers, especially beers of the pilsner type. These foam stabilizers are preferably obtained from hops, which is a constituent that is inherent in beer and accordingly offers the advantage, among others, that the foam stabilizers need to have no negative effect on the taste of the beer. Preferably, the pectins are obtained from hop cones or bines. It may be advantageous to partially saponify (de-esterify) the pectins, in connection with the number of charged groups on the pectins. In addition, the invention provides methods for obtaining the pectins and beverages stabilized with the pectins according to the invention.

Title: Digitally-controlled wide range a.g.c.
IPC: H03G3/20
Filed: 1980-09-10
Abstract: In high speed high quality modems it is important to be able to preserve the gain value for the automatic gain control system during breaks in transmission to permit rapid resumption of normal operation. The a.g.c. circuit comprises a basic a.g.c. transistor amplifier whose emitter-collector conductance is varied by a control voltage derived from the envelope of the amplifier output voltage which is well known. The invention involves the use of a digital-to-analog converter which is controlled by a digital-up-down counter. The counter is controlled by a window comparator which compares the rectified output voltage of the amplifier with a reference voltage level and upper and lower limits. If the output voltage exceeds either limit, the counter is enabled and the appropriate up or down indication is given. The counter is then clocked to change the drive to the d-to-a converter which thereby changes the conductance of the a.g.c. transistor. The state of the up down counter will be used to maintain the a.g.c. at the last level in the event of a transmission break by inhibiting the clock for the counter.

Patent PT-86007-A (PT)
Inventor: CROSSMAN THOMAS
IPC: G07F5/22
Filed: 1987-10-27
Abstract: The coin handling system prevents coin to coin contact taking place in coin operated equipment. This is achieved by an arrangement whereby the presence of a coin activates a lever which then prevents a subsequent coin touching the previous one. A series of such levers are employed in the coin store of coin operated equipment, the actual number depending upon the number of coins to be stored. When the first coin is cleared from the store by a suitable gate arrangement, all coins move along the store by one position, the separation being maintained by the interaction of the levers and coins. The advantages of the system are that a wider range of coins from one coin set can be accommodated in a single store than is presently possible. The coin insertion sequence is maintained for the purposes of microprocessor control since a single store is used. Since coins cannot overtake each other the risk of coin jams is lessened.
